M.V.I. ADULT

Clinical safety rating: caution

Comprehensive clinical and safety monograph for M.V.I. ADULT (M.V.I. ADULT).

How it works

Multivitamin preparation providing essential vitamins (A, D, E, K, C, B1, B2, B3, B5, B6, B12, biotin, folic acid) as cofactors for various metabolic reactions, including energy production, collagen synthesis, antioxidant defense, and blood coagulation.

What the body does with it

Metabolism	Vitamins are metabolized in the liver (e.g., vitamin A to retinoic acid) and other tissues; some undergo hepatic hydroxylation (e.g., vitamin D), conjugation (e.g., folic acid to tetrahydrofolate), or oxidation (e.g., pyridoxine to pyridoxal phosphate).
Excretion	Renal: water-soluble vitamins (B-complex, C) are primarily excreted unchanged in urine; fat-soluble vitamins (A, D, E, K) are excreted in feces via bile. % varies by vitamin: e.g., thiamine 40-60% renal, ascorbic acid 50% renal; vitamin A >80% fecal.
Half-life	Highly variable by component; e.g., ascorbic acid: 8-40 days (depletion), thiamine: 9-18 days, pyridoxine: 2-3 weeks, fat-soluble vitamins: vitamin A: 2-3 months (liver stores), vitamin D: 15-25 days, alpha-tocopherol: 17-19 days, vitamin K: 2-3 hours (short). Clinical context: half-life reflects tissue storage and turnover; chronic dosing leads to accumulation for fat-soluble vitamins.
Protein binding	Variable: vitamin A (retinol) bound to retinol-binding protein (90-95%); vitamin D (25-hydroxycholecalciferol) to vitamin D-binding protein (50-60%); vitamin E (alpha-tocopherol) to lipoproteins (90%); vitamin K to albumin (50-80%). Water-soluble vitamins: minimal binding (<10%).
Volume of Distribution	Not applicable as a mixture; individual vitamins vary: vitamin A: 0.5-1.5 L/kg (liver storage), vitamin D: 0.5-1 L/kg, vitamin E: 5-10 L/kg (adipose tissue), vitamin C: 0.3-0.5 L/kg, B-complex: 0.2-0.5 L/kg. Clinical meaning: reflects distribution into tissues and storage compartments.
Bioavailability	IV only (M.V.I. Adult is for IV use; oral multivitamins have variable bioavailability: water-soluble ~50-90%, fat-soluble 20-50% depending on formulation and food). Not applicable as oral product for this monograph.
Onset of Action	IV: immediate for water-soluble vitamins (minutes to hours) as coenzymes; fat-soluble vitamins require hours to days for biological effect. No oral route for this product.
Duration of Action	Water-soluble vitamins: 1-2 days (excess excreted); fat-soluble vitamins: days to months (liver storage). Clinical: daily dosing required for water-soluble; less frequent for fat-soluble due to storage.

Classification & Brands

Dosing & administration

10 mL intravenously as a single daily dose, administered as an infusion over at least 2 hours. For patients with documented deficiency, dose may be repeated. Route: IV.

Dosage form	INJECTABLE
Renal impairment	No dose adjustment required for renal impairment. Use with caution in patients with severe renal dysfunction due to potential aluminum accumulation from excipients.
Liver impairment	No specific dose adjustment for hepatic impairment. Use with caution in patients with severe hepatic dysfunction due to risk of vitamin accumulation and toxicity.
Pediatric use	For children aged 11 years and older: same as adult dose (10 mL IV once daily). For children 2 to 10 years: 5 mL IV once daily. For infants and children under 2 years: use M.V.I. Pediatric formulation. Administer as infusion over at least 2 hours.
Geriatric use	No specific dose adjustment recommended. Standard adult dose (10 mL IV once daily) is appropriate unless significant comorbidities or polypharmacy warrant caution. Monitor for adverse effects due to potential age-related decline in organ function.

Use during pregnancy

1st trimester	Consult provider

Clinical note

Comprehensive clinical and safety monograph for M.V.I. ADULT (M.V.I. ADULT).

Breastfeeding	M.V.I. ADULT components are excreted into breast milk in amounts that are generally considered safe. No specific M/P ratio available. Use with caution to avoid excessive maternal intake of fat-soluble vitamins.
Teratogenic Risk	M.V.I. ADULT contains multiple vitamins and minerals. At recommended doses, most components are considered safe during pregnancy. However, high dose vitamin A (>10000 IU/day) is teratogenic in first trimester. Vitamin D excess may cause fetal hypercalcemia. No specific trimester risks for standard doses.

Warnings & precautions

■ FDA Black Box Warning

None.

Side Effect Profile

Serious Effects

Absolute Contraindications

Known hypersensitivity to any component; patients with hypervitaminosis; severe renal impairment (due to aluminum content); hemochromatosis (iron-containing component).

Clinical Precautions

Precautions

Hypersensitivity reactions (including anaphylaxis) have been reported; contains aluminum (may be toxic with prolonged use in renal impairment); vitamin K can counteract anticoagulant therapy; vitamin A (retinol) hepatotoxicity with high doses; vitamin D toxicity with excessive doses; folic acid may mask pernicious anemia.
